First Details and Promo Art for the ‘Supergirl’/’Flash’ Crossover

Warner Bros. has unveiled a first look at the hotly anticipated Supergirl/Flash crossover, which features a classic comic book cover featuring the two heroes and the cast of Supergirl along with the tagline: “Who is the fastest person alive? Read…”The Race Between Supergirl & The Flash!”

On the Mar. 28 episode, titled “World’s Finest,” The Flash makes his way over to Supergirl and National City where the two famous superheroes will team up to battle Silver Banshee and Livewire.

The official synopsis provides details about these two universes that have been crafted for the small screen confirming that both the “Arrowverse” (which consists of Arrow, The Flash, and DC’s Legends of Tomorrow) and Supergirl are alternate universes. That surely explains why it’s Grant Gustin’s The Flash making his way over to Supergirl with the introduction of Earth-2 this season.
